BOMB.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed December 13, 1918, Serial No. 266,663. Renewed October31, 1919. Serial No. 334,823.

To all whom. it may concern Be it known that I, JonN GRAUMANN, a

stations, munition dumps and the like, the device belng designed eitherto be dropped from air craft or to be projected from a gun anddelivering inflammable charges in a wayto lnsure the setting on fire ofinflammable structures or material.

The invention provides a device of thecharacter hereinbefore statedwhich in flight will maintain a given position and which when strikingwill become attached to the object struck and cause a confla-gration bysetting the same on fire by the nature of the device.

The drawing illustrates a preferred em bodiment of the invention,however, it is to be understood that in adapting the same to meetdifferent conditions, various changes in the form, proportion, and minordetails of construction may be resorted to without departing from thenature of the invention as claimed hereinafter.

Referring to the accompanying drawing,

Figure 1 is a view in elevation of a bomb embodying the invention.

Fig. 2 is a vertical section on the line 22 of Fig. 1.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.

Corresponding and like parts are referred to in the followingdescription and indicated in the several views of the drawing by likereference characters.

The body of the bomb is indicated at 1 and is preferably made taperingand constructed of inflammable material, such as wood, celluloid or thelike. A central opening 2 is formed in the body 1 and is closed at itsforward end and is designed to receive a charge 3 of inflammablematerial. A fuse 4 leads from the charge 3 and terminate in closeproximity to an igniter 5 which may be of any material. Radial openings6 are formed in the sides of the body 1 near the large or rear endthereof and are adapted to receive cartridges 7 containing inflammablematerial and which are adapted to be projected by explosive charges 8 atthe inner ends of the radial openings 6. Fuses 9 extend from thecartridges 7 and through the explosive charges 8 and terminatecontiguinflammable object with which the charges come in contact.

A head 10 is connected with the forward end of the body 1 in such amanner as to have a limited rearward movement and this head is providedwith a pin 11 whereby the bomb may become attached to the object struckthereby. The head 10 may be retained in position by any suitable meansand as shown wire loops 1:2 are disposed at opposite ends of the head 10and embrace opposite sidesof the body 1, the latter having recesses 13in which the upper ends of the loops 12 are seated. The lower ends ofthe recesses 13 have projections 14L which enter the loops 12 andthereby retain the said loops and head 10 in posit-ion. The loops 12being resilient are retained in position by frictional engagement andspring action.

The igniter comprises the element 5 which may consist of an ignitingsubstance or composition of any nature. A stem 15 receives the igniter 5and is held in a lateral opening formed in the body 1, said openingbeing closed by means of a plug 16 which may be adjusted to bring theelement 5 in proper position to insure ignition. A rod or bar 17 isconnected at one end with the head 10 so as to move therewith andextends into the longitudinal opening2and is roughened at its inner endas indicated at 18 to co-act with the element 5 and insure igniting ofthe fuses 4 and 9. The roughened surface 18 may be of steel and theelement 5 of a nature to co-act with the roughened steel surface toproduce a stream of sparks in a manner well understood in ignitingdevices so as to fire the fuses 4E and 9 or the element 5 may consist ofa composition such as employed in the manufacture of matches and whichis adapted to be lighted by the rubbing action of the part 18 when thehead 10 is moved rearward.

A tube-19 is applied to the rear end of the head 1 and may consist of acylinder of card board or other light and cheap material. The rear endof the body 1 is reduced and receives the end of the tube 19. The tube19 is of a length to insurethe traveling of the bomb in a direct courseand with the head 10 foremost.

The bomb may be dropped from air craft or may be projected by means of agun and its construction is such that when it strikes an object itbecomes attached thereto by means of the point 11 and the impact causesthe head 10 to relatively move rearward with the result that the igniteris brought into operation and lights the fuses 4c and 9 whereby thecartridges 7 are projected and because of their inflammable nature seton fire the object with which they come in contact. After the cartridges7 have been projected the explosive and inflammable charge 3 is ignitedand causes an additional fire by reason of the inflan'in'iable nature ofthe charge 3 and the nature of the body 1.

The foregoing description and the drawings have reference to what may beconsidered the preferred, or approved, form of my invention. It is to beunderstood that I may make such changes in construction and arrangementand combination of parts, materials, dimensions, et cetera, as may proveexpedient and fall within the scope of the appended claims.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent is l. Abomb,- comprising a body containing a charge, a head movable Withreference to the body, resilient elements connected with the head andembracing opposite sides of opening, an igniting element adjacent theends of the several fuses, a movable head and a member movable with thehead and adapted to cooperate with the igniting elc ment to effect alighting of the fuses.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN GRAUMANN.
